2.2 SETTING ID CODES TO FACSIMILE
MACHINES

Brother facsimile machines are assigned unique ID codes (character strings) at the factory. If you
replace the main PCB of the machine, the machine will lose its assigned ID code so that it will not
be identified by the connected PC*.

You need to assign a unique ID code (character string) to the machine according to the procedure
given here. For models covered by this manual, set serial numbers given to individual machines as
ID codes.

(*ID codes are essential when more than one machine is connected to a single PC via USB.)

Connecting the facsimile machine to your PC (See the illustration on page 2-1 )

(1) Make sure that your PC is turned off.

(2) Make sure that the power cord of the facsimile machine is unplugged from a wall socket or
other power source.

(3) Connect the interface cable to the parallel interface port on the back of the facsimile machine
and secure it with the lock wires.

(4) Connect the other end of the interface cable to the printer port of your PC and secure it with
the two screws.

(5) While holding down the Menu key, plug the machine's power cord into a wall socket or other
power source.

(6) Turn on your PC.

Running the setup utility

(1) On your PC, run the ID/head property setup utility (BRUSBSN.EXE). The following window
will appear.

2.3 UPDATING HEAD PROPERTY INFO STORED
IN THE FACSIMILE MACHINE

To keep the print quality, the controller optimizes the head drive strength, ink jet-out timing, and
other drive conditions according to the electromechanical properties unique to individual print
heads and ambient temperature. The head property information is stored in the EEPROM of the
main PCB.

If you replace the print head unit and/or main PCB of the machine, then you need to update head
property information according to the procedure given here.

TIP: The updating procedure given here uses a PC. For the updating procedure in the maintenance
mode without using a PC, refer to CHAPTER 5, Subsection 5.3. 14.

Connecting the facsimile machine to your PC (See the illustration on page 2-1 )

(1) Make sure that your PC is turned off.

(2) Make sure that the power cord of the facsimile machine is unplugged from a wall socket or
other power source.

(3) Connect the interface cable to the parallel interface port on the back of the facsimile machine
and secure it with the lock wires.

(4) Connect the other end of the interface cable to the printer port of your PC and secure it with
two screws.

(5) While holding down the Menu key, plug the machine's power cord into a wall socket or other
power source.

3.2.1 Scanner Mechanism

This mechanism consists of the document guide base, ADF & document tray ASSY and scanner
unit.

The ADF (automatic document feeder) unit contains a separation roller ASSY, document feed
roller ASSY, document ejection roller, ADF motor, and document front and rear sensors.

The scanner unit consists of a scanner top cover, CCD unit, CCD drive mechanism, CCD HP
sensor, and scanner base.

For details about the sensors, refer to Subsection 3.2.3.

This scanner mechanism supports a dual scanning system.

(1) If you set documents on the document guide base with their faces up and start the scanning
operation, then the ADF motor rotates to pull in those documents into the ADF unit, starting
from the top sheet to the bottom, page by page. Each document curves downwards and turns to
the right with the document feed roller so as to advance above the CCD unit, and then it is fed
out to the document tray with the document ejection roller ASSY.

This way, documents move above the CCD unit being kept in a stationary position.

(2) If you open the ADF & document tray ASSY, put a sheet of document (or put a bound book
opened) on the glass of the scanner top cover, close the ADF & document tray ASSY, and
start the scanning operation, then the CCD drive mechanism will be driven.

The CCD motor built in the CCD unit rotates. As illustrated below, the CCD drive gear and
idle pulley carry the CCD drive belt on the underside of the CCD unit, so clockwise and
counterclockwise rotations of the CCD motor move the CCD unit to the right and left,
respectively.

In this scanning system, the CCD unit moves horizontally beneath a document being kept in
stationary position.

The CCD unit contains a charge coupled device (CCD) image sensor. The cold-cathode
fluorescent lamp illuminates a document and the reflected light of the scanned image data is
transmitted via the mirrors into the lens which reduces the scanned data so as to form the image on
the CCD.

3.2.2 Ink Jet Printing Mechanism

3.2.2.1 Paper pulling-in, registration, feeding, and ejecting mechanisms

The paper pulling-in, registration, feeding, and ejecting mechanisms are driven by a single paper
feed motor located at the left side of the main chassis via the gear train. (See the illustration given
on the next page.)

First, the paper feed motor rotates clockwise (when viewed from the output gear). The rotation is
transmitted to the PF roller gear that rotates paper feed roller. At the right end of the paper feed
roller is the PF roller gear R which is always engaged with the ASF/purge idle gear. Engaged with
the ASF/purge idle gear, the ASF-purge switching gear 23 transmits the rotation via gear 25 and
the ASF gear train to the ASF roller unit. This way, the ASF roller will pull in paper.

When the ASF roller is pulling in paper, the paper feed roller rotates in the backward direction to
register the leading edge of the pulled-in paper.

Next, the paper feed motor rotates counterclockwise to rotate the paper feed roller in the forward
direction. The paper will advance through the paper path. During the paper feeding operation, no
rotation is transmitted to the ASF roller because of the planetary gear system built in the ASF
roller unit.

The above paper pulling-in and feeding operations take place when the carriage is in printing
operation. If the carriage reaches the purge position, the ASF-purge switching gear 23 will be
disengaged from the gear 25 and engaged with purge bevel gear A. For the purging mechanism,
refer to Subsection 3.2.2.3.

Print head unit

(1) Print head unit

This machine uses drop-on-demand ink jet printing. Each of the right and left print heads has an
ink-jet unit that has a pair of nozzle columns for two color inks. A nozzle column consists of 75
nozzles, 75 channels covered with piezoelectric ceramic (PZT), a manifold, and filter. As
illustrated below, the pair of nozzle columns is staggered.

If the controller issues a print command, a biased voltage will be applied to all electrodes formed
on the surface of the piezoelectric ceramic so that each actuator will be distorted as shown with
broken lines.

If the electrodes on a target channel are deenergized according to drive signals, then the associated
piezoelectric ceramic actuator returns to the previous form so that the ink in the manifold will be
vacuumed out to the channel.

If the voltage is applied again, the piezoelectric ceramic actuator will be distorted again to apply
pressure to the ink in the channel, causing the ink to jet out through the nozzle. The jetted-out ink
drop will be splashed and produce a dot on paper held by the platen.

As the carriage holding the print head unit travels at the printing speed, the controller sends print
command pulses to the piezoelectric actuator driver circuit embedded in the print head unit.

(2) Ink cartridges

The machine uses four ink cartridges (black, cyan, yellow, and magenta) of disposable type to
supply ink to the print head unit. As shown below, an ink cartridge contains an ink-impregnated
urethane foam. If ink-jet print operation or purging operation takes place, ink comes out of the
urethane foam and is supplied to the print head unit through the ink room, filters, and manifold.

For the ink cartridge sensors on the carriage PCB, refer to Subsection 3.2.3.

Shown below is a head cap mechanism that prevents the nozzles of the print heads from drying up
when they are not in use.

Upon completion of printing, the carriage travels to the right and moves the head cap holder
provided on the purge unit to the right together. In the head cap holder is a head cap unit which is
supported with a lift lever. The rightward movement of the head cap holder turns the lift lever and
pushes up the head cap unit to the position where the head caps come into tight contact with the
print heads. This way, the nozzles will be capped.

3.2.2.3 Purging mechanism

The purge mechanism is driven by the paper feed motor located at the left side of the main chassis.

As described in Subsection 3.2.2.1, the motor rotation is transmitted to the ASF/purge idle gear at
the right side of the main chassis. Engaged with the ASF/purge idle gear, the ASF-purge switching
gear 23 works as a clutch gear.

When the carriage travels from the left to right to reach the purge position, the tab provided on the
back of the carriage pushes the purge lever on the main chassis to the right (see the illustration
below). Accordingly, the ASF-purge switching gear 23 (which was shifted to the left by the purge
lever) will move to the right by the switching gear spring so as to become disengaged from the
gear 25 and engaged with the purge bevel gear A. (See the illustration given on the next page.)
This engagement will transmit the motor rotation to the purge bevel gear B on the purge unit. This
way, when the carriage is in the purge position, the motor rotation is transmitted to the purge unit.

On the contrary, if the carriage travels from the purge position to the left, the tab on the back of the
carriage releases the purge lever which will be pulled back to the left. The ASF-purge switching
gear 23 will be disengaged from the purge bevel gear A.

purge bevel gear A.

When the motor rotation is transmitted to the purge unit, its counterclockwise rotation will drive

the purge cam and its clockwise rotation, the pump switching unit (when viewed from the output

gear of the motor).

The purge cam is so designed that:

- the carriage lock pops out to lock the carriage before purging and pops in before cleaning with
the head wiper (see the illustration below),

- the pump works to draw out ink from each of the four head nozzles and drain it to the ink
absorber felts, and

- the head wiper comes out to clean the nozzle surface (see the illustration below).
The pump switching cam is so designed that:

- the pump switching unit switches application of the pump's negative pressure between the four
head nozzles in the order of black, cyan, yellow, and magenta nozzles. When the pump
switching cam is in the home position, normal atmospheric pressure will be restored.

The home position of the purge cam and pump switching cam are detected by their HP switches.
For those switches, refer to Subsection 3.2.3.

(1) Carriage lock

If the purge cam is driven, the carriage lock of the purge unit pops out and locks the carriage to
align ink-jet units with the mating head caps during purge operation. After purging but before
cleaning with the head wiper, it pops in to release the carriage. When the power is off, the carriage
lock keeps the print heads pressed against the head caps.

(2) Purging

If activated, the pump draws out ink to purge air bubbles or dust from the inside of the head
nozzles and channels. As the purge cam rotates by one turn, the piston of the pump reciprocates
two strokes. To complete purging of all four nozzles and channels, the purge cam rotates by two
turns ad the piston reciprocates four strokes.

(3) Draining

The pump drains drawn ink into the ink absorber felts.

(4) Cleaning with the head wiper

After purging operation, the head wiper comes out and the carriage moves from the right to left so
as to clean ink remaining on the heads' surface.

(5) Restoring the pump's pressure to normal atmospheric pressure

When the pump switching cam is in the home position, the controller stops to produce negative
pressure and restore the pump's pressure to normal atmospheric pressure.

3.2.2.4 Carriage drive mechanism

The carriage motor controls horizontal motion. The motor rotation is transmitted via the motor
pulley to the timing belt.

The carriage, which is supported and guided by the carriage rail, is secured to the timing belt.
Clockwise and counterclockwise rotations of the carriage motor move the carriage to the right and
left, respectively.

On the back of the carriage is the carriage encoder which tells the control circuitry the current
carriage position counted based on the carriage motor position by using the encoder strip attached
to the main chassis.

Document front sensor which detects the presence of documents.

Document rear sensor which detects the leading and trailing edges of pages to tell the control
circuitry when the leading edge of a new page has reached the starting position and when the
scan for that page is over.

Document tray open sensor which detects whether the document tray is closed.

Scanner open sensor which detects whether the scanner unit is closed.

Registration sensor which detects the leading and trailing edges of paper, which allows the
controller to determine the registration timing and check paper jam.

Paper width sensor which detects whether the paper width is "A4-size or wider" or "narrower
than A4-size."

CCD HP sensor which detects whether the CCD unit is placed in the home position.

Ink empty sensor which detects at the start of printing whether any of the four ink cartridges is
near empty. According to this sensor signal, the controller may display "NEAR EMPTY XXX"
message.

Ink cartridge sensors, each of which detects whether an ink cartridge is loaded.

Carriage encoder which detects the current carriage position and carriage travel speed. If the
carriage travels speed varies abnormally, the controller regards it as a paper jam.

Head thermister which allows the controller to control the temperature of the print heads.
According to the change of the thermister's internal resistance monitored, the control circuitry
regulates the drive voltage applied to the piezoelectric ceramic actuators on each print head
since the viscosity of the ink varies depending upon the temperature.

4.1 DISASSEMBLY/REASSEMBLY

■ Safety Precautions

To prevent the creation of secondary problems by mishandling, observe the following precautions
during maintenance work.

(1) Unplug the power cord from the power outlet before replacing parts or units. When having
access to the power supply, be sure to unplug the power cord from the power outlet.

(2) Be careful not to lose screws, washers, or other parts removed for parts replacement.

(3) Do not remove gears from the document feed roller ASSY or ejection roller ASSY if at all
possible. Once removed, they will become unusable and new gears will have to be put back in.

(4) When using soldering irons and other heat-generating tools, take care not to damage the resin
parts such as wires, PCBs, and covers.

(5) Before handling the PCBs, touch a metal portion of the machine to discharge static electricity;
otherwise, the electronic parts may be damaged due to the electricity charged in your body.

(6) When transporting PCBs, be sure to wrap them in conductive sheets such as aluminum foil.

(7) Be sure to reinsert self-tapping screws correctly, if removed.

(8) Tighten screws to the torque values listed on the next page.

(9) When connecting or disconnecting cable connectors, hold the connector bodies not the cables.
If the connector has a lock, always slide the connector lock to unlock it.

(10) Before reassembly, apply the specified lubricant to the specified points. (Refer to Subsection
4.2 in this chapter.)

(11) After repairs, check not only the repaired portion but also that the connectors and other related
portions function properly before operation checks.

(12) Once the print head unit prints, it will start head locking operation after five seconds from the
end of printing. The head locking operation will take 5 to 10 seconds. NEVER unplug the
power cord before the machine completes the head locking operation; doing so will make the
print head unit unusable and require replacement with a new print head unit.

When you receive the machine from the user or when you pack it for sending it back to the
user, check the head locking state.

(1 byte)

b) Max. allowable value of a) above (1 byte)

c) Voltage divider ON/OFF level for red image ( 1 byte)

d) Voltage divider ON/OFF level for green image (1 byte)

e) Voltage divider ON/OFF level for blue image (1 byte)

f) Voltage divider ON/OFF level for monochrome image (1 byte)

g) Compensation data for background color (1 byte)
h) Black level data for red image (16 bytes)

i) Black level data for green image (16 bytes)
j) Black level data for blue image (16 bytes)
k) White level data for red image (4896 bytes)
1) White level data for green image (4896 bytes)

6.2 TROUBLESHOOTING

6.2.1 Introduction

This section gives the service personnel some of the troubleshooting procedures to be followed if
an error or malfunction occurs with the facsimile equipment. It is impossible to anticipate all of the
possible problems which may occur in future and determine the troubleshooting procedures, so this
section covers some sample problems. However, those samples will help service personnel
pinpoint and repair other defective elements if he/she analyzes and examines them well.

6.2.2 Precautions

Be sure to observe the following to prevent the secondary troubles from happening:

(1) Always unplug the AC power cord from the outlet when removing the covers and PCBs,
adjusting the mechanisms, or conducting continuity testing with a circuit tester.

(2) When disconnecting the connectors, do not pull the lead wires but hold the connector
housings.

(3) • Before handling the PCBs, touch a metal portion of the machine to discharge static

electricity charged in your body.

• When repairing the PCBs, handle them with extra care.

After repairing the defective section, be sure to check again if the repaired section works correctly.
Also record the troubleshooting procedure so that it would be of use for future trouble occurrence.

• Selectors 1 through 3: 1st dial tone detection

These selectors activate or deactivate the 1 st dial tone detection function which detects the 1 st dial
tone issued from the PSTN when a line is connected to the PSTN.

Setting all of these selectors to " 1 " activates the dial tone detection function so that the equipment
starts dialing upon detection of a dial tone when a line is connected. (However, in those countries
which support no dial tone detection function, e.g., in the U.S.A., setting these selectors to "1"
makes the equipment start dialing after a WAIT of 3.5 seconds.) For the detecting conditions of the
1st dial tone, refer to WSW07 and WSW08.

Other setting combinations deactivate the dial tone detection function so that the equipment starts
dialing after the specified WAIT (3.5, 7.0, 10.5, 14.0, 17.5, 21.0, or 24.5 seconds) without
detection of a dial tone when a line is connected to the PSTN.

• Selector 4: Max. pause time allowable for remote ID code detection

This selector sets the maximum pause time allowable for detecting the second digit of a remote ID
code after detection of the first digit in remote reception.

If selector 4 is set to "0" (2 seconds), for instance, only a remote ID code whose second digit is
detected within 2 seconds after detection of the first digit will become effective so as to activate
the remote function.

• Selectors 5 and 6: Busy tone detection in automatic sending mode

These selectors determine whether or not the equipment automatically disconnects a line upon
detection of a busy tone in automatic sending mode.

Setting selector 6 to "0" ignores a busy tone so that the equipment does not disconnect the line.

Setting selectors 5 and 6 to "0" and "1," respectively, makes the equipment detect a busy tone only
after dialing and disconnect the line.

Setting both of selectors 5 and 6 to "1 " makes the equipment detect a busy tone before and after
dialing and then disconnect the line.

• Selector 7: Busy tone detection in automatic receiving mode

This selector determines whether or not the equipment automatically disconnects the line upon
detection of a busy tone in automatic receiving mode.

When these selectors are set to "1, 1, 0":

If you press the Pause key in pulse dialing, the equipment will first wait for
the 2nd dial tone to be sent via the communications line. After that, pressing
the Pause key will cause the equipment to insert a WAIT of 3.5 seconds. In
tone dialing, the equipment will insert a WAIT of 3.5 seconds.

When these selectors are set to "1, 1, 1":

If you press the Pause key, the equipment will first wait for the 2nd dial tone
to be sent via the communications line regardless of pulse dialing or tone
dialing. After that, pressing the Pause key will cause the equipment to insert a
WAIT of 3. 5 seconds.

(In those countries where no dial tone detection function is supported, setting
these selectors to "1, 0, 1," "1, 1, 0," or "1, 1, 1" inserts a WAIT of 3.5
seconds.)

Selectors 4 through 6: Detection of international tone

Upon detection of the 2nd dial tone for the time length specified by these selectors, the equipment
starts dialing.

This setting is effective only when the 2nd dial tone detection function is activated by selectors 1
through 3 (Setting 101, 1 10, or 1 1 1).

This function does not apply in those countries where no dial tone detection function is supported.

NOTE: Selectors 1 through 5 are not applicable in those models which do not support ECM.

• Selector 1: Frame length selection

Usually a single frame consists of 256 octets (1 octet = 8 bits). For communications lines with
higher bit error rate, however, set selector 1 to " 1 " so that the facsimile equipment can divide a
message into 64-octet frames.

Remarks: The error correction mode (ECM) is a facsimile transmission manner in which the
equipment divides a message into frames for transmission so that if any data error occurs on the
transmission line, the equipment retransmits only those frames containing the error data.

• Selector 2: Use of non-standard commands

If this selector is set to "0," the equipment may use non-standard commands (the machine's native-
mode commands, e.g., NSF, NSC, and NSS) for communications. If it is set to "1," the equipment
will use standard commands only.

• Selectors 3 and 4: No. of retries

These selectors set the number of retries in each specified modem transmission speed.

• Selector 5: T5 timer

This selector sets the time length for the T5 timer.

• Selector 6: T1 timer

This selector sets the time length for the Tl timer.

• Selectors 7 and 8: Elapsed time for time-out control

If the equipment receives no response (no G3 command) from the called terminal in automatic
sending during the time set by these selectors, it disconnects the line.

Selectors 1 through 6: First and last choices of transmission speed for fallback

These selectors are used to set the MODEM speed range. With the first transmission speed choice
specified by selectors 1 through 3, the equipment attempts to establish the transmission link via the
MODEM. If the establishment fails, the equipment automatically steps down to the next lowest
speed and attempts to establish the transmission link again. The equipment repeats this sequence
while stepping down the transmission speed to the last choice specified by selectors 4 through 6.

If the MODEM always falls back to a low transmission speed (e.g., 4,800 bps), set the first
transmission speed choice to the lower one (e.g., modify it from 12,000 bps to 7,200 bps) in order
to deactivate the high-speed MODEM function and reduce the training time for shorter
transmission time.

Generally, to save the transmission time, set the last transmission speed choice to a higher one.

• Selector 1: EP tone prefix

Setting this selector to "1" makes the equipment transmit a 1700 Hz echo protection (EP) tone
immediately preceding training in V.29 modulation system to prevent omission of training signals.

Prefixing an EP tone is effective when the equipment fails to transmit at the V.29 modem speed
and always has to fall back to 4800 bps transmission.

• Selectors 2 and 3: Overseas communications mode

These selectors should be used if the facsimile equipment malfunctions in overseas
communications. According to the communications error state, select the signal specifications.

Setting selector 2 to "1 " allows the equipment to use 1100 Hz CED signal instead of 2 1 00 Hz in
receiving operation. This prevents malfunctions resulting from echoes, since the 1100 Hz signal
does not disable the echo suppressor (ES) while the 2100 Hz signal does.

Setting selector 3 to " 1 " allows the equipment to ignore a DIS signal sent from the called station
once in sending operation. This operation suppresses echoes since the first DIS signal immediately
follows a 2100 Hz CED (which disables the ES) so that it is likely to be affected by echoes in the
disabled ES state. However, such a disabled ES state will be removed soon so that the second and
the following DIS signals are not susceptible to data distortion due to echoes. Note that some
models when called may cause error by receiving a self-outputted DIS.

• Selectors 8: CNG detection on/off

If this selector is set to "1," the equipment detects a CNG signal according to the condition preset
by selectors 2 and 3 of WSW18 after a line is connected. If it is set to "0," the equipment detects a
CNG signal as long as the line is connected.

• Selector 1 : Starting point of training check (TCF)

At the training phase of receiving operation, the called station detects for 1 .0 second a training
check (TCF) command, a series of zeros which is sent from the calling station for 1.5 seconds to
verify training and give the first indication of the acceptability of the line.

This selector sets the starting point from which the called station should start counting those zeros.
If this selector is set to "0," the called station starts counting zeros 100 ms after the head of a series
of zeros is detected.

If it is set to "1," the called station starts counting zeros upon detection of 10-ms successive zeros
50 ms after the head of a series of zeros is detected. In this case, if the detection of 10-ms
successive zeros is too late, the data counting period will become less than 1 .0 second, making the
called station judge the line condition unacceptable.

• Selectors 2 and 3: Allowable training error rate

The called station checks a series of zeros gathered in training (as described in Selector 1)
according to the allowable training error rate set by these selectors. If the called station judges the
line condition to be accepted, it responds with CFR; if not, it responds with FTT.

• Selectors 4 and 5: Decoding error rate for transmission of RTN

The facsimile equipment checks the actual decoding errors and then transmits an RTN according
to the decoding error rate (Number of lines containing an error per page + Total number of lines
per page) set by these selectors.

• Selector 8: Limitation of attenuation level

Setting this selector to "0" limits the transmitting level of the modem to 10 dB.

NOTE: Selector 5 is applicable only to the U.S.A. versions.

• Selector 2: Default reduction rate for failure of automatic reduction during recording

This selector sets the default reduction rate to be applied if the automatic reduction function fails
to record one-page data sent from the calling station in a single page of the current recording
paper.

If it is set to "0," the equipment records one-page data at full size (100%) without reduction; if it is
set to "1," the equipment records it at 70% size.

• Selector 5 Minimum short-OFF duration in distinctive ringing

The ringer pattern consists of short and long rings, e.g., short-short-long rings. This selector sets
the minimum OFF duration following a short ring in order to avoid missing ringer tones in
distinctive ringing.

If this selector is set to "1," when the short-OFF duration is a minimum of 90 ms long, then the
equipment will interpret the short-OFF as OFF.

*ECP (Enhanced Capabilities Port)

• Selector 1: ECP mode

The ECP mode enhances the normal bidirectional communications between the facsimile
equipment and the connected PC for higher transmission speed.

• Selector 2: Recovery from Inactive PC Interface

If the facsimile equipment recognizes via the STB signal line that the connected PC is powered off,
it will turn the PC interface outputs Low to protect the PC from hazards that could be caused by
weak electric current accidentally flown from the equipment.

This selector determines whether the equipment should recover from the inactive PC interface to
normal interfacing state upon receipt of data from the PC.

• Selector 3: PC Power-off Recognition Time

This selector sets the time length from when the equipment detects the PC powered off until it
recognizes the detected state as power-off.

If selector 2 is set to "0," it is recommended that selector 3 be set to "1"; otherwise, the equipment
may mistakenly detect PC powered off.

• Selector 5: Escape from phase C

This selector determines whether or not the equipment will escape from phase C when it detects an
RTC (Return to Control) in non-ECM mode or an RCP (Return to Control Partial page) in ECM
mode.

• Selectors 6 through 8: Lower limit of frequency to be ignored after detection of calling signals (Ci)

At the start of reception, if the equipment detects the frequency of calling signals (Ci) specified by
selectors 1 through 4 of WSW14, it will start the ringer sounding. When doing so, the equipment
may fail to detect the calling signals normally due to noises superimposed at the time of reception.
To prevent it, use selectors 6 through 8 of WSW36.

If the equipment detects higher frequencies than the lower limit specified by these selectors, it will
regard them as noise and interpret that detecting state as being normal, allowing the ringer to keep
sounding (until the equipment starts automatic reception of FAX data if in the FAX mode or enters
the TAD mode if set in the TEL mode, according to the preset number of ringers).

transmitted normally.

• Selector 2: Erasure of the stored image data of an unsent document at the time of the subsequent

in-memory message transmission

If in-memory message transmission fails repeatedly when selector 1 is set to "1," the temporary
memory will be occupied with image data. Setting selector 2 to "1" will automatically erase the
stored 1 st-page image data of an unsent document at the time of the subsequent in-memory
message transmission only when recording paper or toner runs out.

If you set documents in the ADF and the document front sensor detects them or if you open the
document tray ASSY and the document tray open sensor detects the open state, then the controller
will make correction of the reference voltage to be applied to white level compensation for
document scanning before the Copy button is pressed.

These selectors determine how long compensation data obtained beforehand will keep effective.

NOTE: WSW45 is applicable only to models equipped with a flat-bed scanner.

• Selectors 1 through 3: Delay time from when documents are set until the ADF starts drawing them in

These selectors determine how long the ADF will delay automatic drawing-in of documents (to the
scanning standby position) after you set them in the ADF, as well as determining whether or not
the ADF automatically draws in documents.

Selectors 4 through 6:

Periodical correction intervals of the reference voltage applied to white level
compensation for document scanning, during standby

These selectors set the correction intervals (in seconds) of the reference voltage to be applied to
white level compensation for document scanning during standby, as well as determining whether
or not the controller makes the reference voltage correction during standby. (Conventionally, the
correction has been made immediately before the start of actual scanning)

This function takes effect in copying. Making the correction during standby may shorten the
preparation time for copying.

NOTE: Do not access these selectors.

Selector 7: Standby position of the CCD unit

This selector determines whether the standby position of the CCD unit should be the home
position or the location of the white -level reference film (attached to the inside of the scanner top
cover). If the location of the reference film is selected, the CCD unit will not return to the home
position so as to shorten the travel time, decreasing the preparation time for copying.

For the related functions, refer to WSW36, selectors 2 and 3.

• Selector 3: Parallel port output pins kept at high level

Setting this selector to "0" will keep all parallel output pins of the facsimile equipment at high
level. Use this setting if Resource Manager (bundled with MFC models) installed to WindowsNT
running on the connected PC fails to monitor the power ON/OFF state of the facsimile equipment.

• Selectors 6 through 8: Delay time at the start of scanning for making a single copy

According to the setting made by these selectors, the MFC models may delay the scanning start
timing to prevent the carriage drive vibration from affecting the document scanning. No setting
change is required unless otherwise specified by Brother.

Selector 1 : Handling paper at the occurrence of a paper feed timing error

When feeding paper to the print start position, the equipment might cause a feed timing error so
that the registration sensor goes ON signaling the presence of paper. This selector determines
whether the equipment will print on the current paper or eject the current paper without printing
and print on the next paper.

Selectors 3 and 4: Delay of FAX line disconnection when switching to the pseudo-ringing external
telephone

When the equipment receives a phone call, it can make the connected external telephone ring (so
called pseudo-ringing). During pseudo-ringing, if you pick up the handset of the external
telephone, the line might be disconnected due to cut-off of the line current.

To hold the line, the equipment may supply line current by making use of the pulse generator
circuit that forms a parallel loop. This way the FAX line disconnection may be delayed. These
selectors determine the delay period.
